Role needed to migrate projects in VBCS

I had a query related to the role of the non-SSO user that we use when we migrate a project in VBCS. So, in the environment tab in VBCS, in the source instance, we add the target environment URL and non-SSO user credentials who has access to the target instance. Are there any specific roles that this user should have or are there any specific criteria that this user should fulfil (we are only aware that it should be a non-SSO user)
